actually ia is the field which might be NULL.
If this is similar to other cases, it should occur with icmp
packets.
Someone seeing the problem might try to add a check for ia==NULL,
comment out the per-address statistics, and see if the check
triggers for some kind of packets.

(2:40am here so don't ask me to try it now...)
